...experience to feel as sleek and effortless as the clothes themselves. Think the clean aesthetic and snappy performance of Bewakoof, but tailored to our own brand voice. Here’s what I need from you: • A custom Shopify theme built for speed, fully responsive across devices, and visually minimalist—ample white space, crisp typography, and high-impact product imagery. • Liquid, HTML/CSS, and JavaScript work for any bespoke front-end components (lookbooks, size-guide pop-ups, smart search, etc.). • A streamlined admin panel so my team can add products, manage inventory and run promotions without touching code. If an app or custom section makes day-to-day easier, suggest it. • Secure, scalable back-end configuration, including optimisation for Co...
...an internship, I expect the same calibre of execution I would demand from any senior engineer—clean, maintainable code, proactive communication, and ownership of outcomes. The scope centres on building and refining web features for our live platform. Exact modules will be agreed once you review the current codebase, but the work sits squarely in modern web stacks, so fluency with HTML5, CSS3, JavaScript/TypeScript, at least one front-end framework (React, Vue, Angular, or similar), plus server-side logic in Node.js, Python, or comparable technology is essential. Strong Git habits and comfort with agile sprints will make collaboration smooth. What you’ll hand off to me: • A working, deployable web module (or set of modules) merged into our repository • In...
...move my static site to the next level. The priority is a smooth, intuitive user experience, backed by a modern-and-professional look that feels alive rather than flat. Here’s what I need from you: • A fresh UI crafted around UX best practices, presented first as high-fidelity Figma (or similar) mock-ups. • Responsive front-end code that brings those screens to life—clean HTML5, CSS3/Sass, and JavaScript (React, Vue, or vanilla; I’m flexible as long as the result is lightweight and maintainable). • Thoughtfully placed interactive elements and dynamic content areas so sections can update without a full page reload. I’ll supply existing brand assets and page content; you’ll handle the visual overhaul, component styling, and the co...
I run a fully custom-built e-commerce site and need a developer who can keep it healthy, secure, and evolving. The back-end is mainly PHP, several Python micro-services handle data tasks, and the front-end relies on JavaScript. Because the codebase was written from scratch—not on Shopify, WooCommerce, or Magento—every update requires someone comfortable tracing bespoke logic rather than relying on plug-ins. Typical work you’ll tackle includes bug fixes, performance tuning, adding new product or checkout features, tightening security, and occasionally integrating third-party APIs or payment gateways. I use Git for version control and stage all changes in a test environment before we push live, so familiarity with that workflow is a must. Deliverables will usually ...

Documentation: A concise README detailing how to update search parameters and selectors when the site layout changes. Reporting: An automated runtime log summarizing total pages sc...
I want a clean, responsive portfolio site built from the ground up. The heart of the project is a gallery / showcase of my work that looks polished on both desktop and mobile, loads fast, and is easy for me to update later. Here’s what matters most to me: • Modern, lightweight code (HTML5, CSS3, JavaScript; I’m open to React, , or a static-site setup if it keeps things swift). • Simple way for me to add new projects after launch—Markdown, a lightweight headless CMS, or another hassle-free method. • Solid SEO fundamentals, smooth page-load performance, and subtle animations that enhance (but don’t distract from) the work on display. Please share links to portfolio sites you have already delivered, specify the tech stack you recommend, ou...

...to save, rename, and reopen multiple layouts is essential, whether that’s through browser local storage, small JSON files, or another lightweight method you prefer. I’m flexible on how the app is delivered: a lightweight web page, an Electron desktop build, or even a mobile-friendly PWA could all work—whichever approach keeps performance smooth and avoids heavyweight installs. Well-structured JavaScript/TypeScript, HTML5 Canvas or SVG, and a clean UI framework such as React, Vue, or plain vanilla are all acceptable. Deliverables • Interactive 2D floor-plan viewer populated with my supplied drawing • Resizable drag-and-drop furniture shapes (basic outlines) • Save / load mechanism for multiple named layouts • Documentation covering b...

...structure and core functionality are already in place; what I need now is a modern, cohesive design that feels fresh on both desktop and mobile. Here’s the essence of the job: • Audit the current pages, spot outdated layouts or styling inconsistencies, and propose a cleaner UI/UX direction. • Implement the approved design using standards-compliant HTML, CSS, and, where helpful, lightweight JavaScript. I prefer solutions that keep load times fast and code easy to maintain. • Ensure the new look renders flawlessly across major browsers and common screen sizes. While my immediate priority is design changes, I’m open to your suggestions if you notice small tweaks that could improve user flow along the way. When we wrap up, I expect the updated the...
...and responsive so it looks identical on desktop, tablet, and mobile. A prominent hero section, a concise value proposition, and a frictionless contact/opt-in form are must-haves. Subtle micro-animations or scroll effects are welcome as long as they keep the interface light. You will handle the full front-end build—HTML5, CSS3 (or a lightweight utility framework such as Tailwind), and vanilla JavaScript or your preferred modern JS library—as long as the final code is lean and easily hand-offable. No CMS integration is required for this phase, just a polished static page I can drop onto my server. Please include links to past work that showcases similar lead-gen pages or minimalist UI projects. I will shortlist based on visual quality, load speed, and how smoothly you...
I have a JavaScript automation script that drives Automating repetitive tasks and it is almost complete. The code lives in my “Java Script” editor environment and runs correctly until one particular step, where it freezes. Once that obstacle is removed, the same logic simply needs to repeat for every row found in an existing Excel file. Here is what I need from you: connect with me on a live Zoom session right away, locate the exact point of failure, debug it in real time, and verify that the script loops flawlessly through all Excel rows. Payment will be released only after we see the script run end-to-end without manual intervention; if it still stalls, no funds will be issued. If you are absolutely confident in rapid JavaScript debugging, comfortable shari...

Please build it with real-time readiness in mind; even though live updates weren’t selected today, I want the codebase structured so WebSocket or long-polling can be dropped in later without a rewrite.

I need a complete payment-aggregation solution that lets my merchants accept Credit/Debit Cards, Digital Wallets and Bank Transfers through a single, secure interface. Core requirements are a real-time fraud-detection layer and a fully automated recurring-payments module, both exposed via clean REST/JSON endpoints and an easy-to-embed JavaScript/SDK bundle. Your build must slot smoothly into three environments I already run—standard e-commerce sites, native iOS/Android apps and in-store POS terminals—so consistent API behaviour, webhooks and mobile-ready SDKs are critical. If you’ve previously unified these channels you’ll know the importance of tokenisation, PCI-compliant vaulting and clear onboarding flows for merchants; please weave those into the archite...
I have complete high-fidelity page mock-ups, brand guidelines, and all copy ready for Capital Spring, a UK business-funding company. Your task is to turn those visuals into a production-ready site that mirrors the designs pixel-perfectly while feeling fast, fluid, and premium on every screen size. Preferred stack is a modern JavaScript framework—React, Vue, or Angular—so that future feature work and component reuse stay simple. If you favour another SPA approach I’m open to hearing why it might serve us better, but the end result must load quickly, score well on Core Web Vitals, and be easy for my team to maintain. Primary objective: generate qualified funding enquiries. Every design element therefore needs clean semantic markup, logical heading hierarchy, and on...
